How to use

Connect the Fanvil A12 to the local network using an Ethernet cable; when connected to a PoE-capable switch or injector the device receives power and network access through the same cable. Register the unit with your SIP server or VoIP provider following standard SIP account setup steps. Place the unit on a desk or mount it on a wall at an appropriate height for users to speak into the microphone and hear through the speaker. Use the speakerphone to initiate and receive calls; the full-duplex audio supports natural conversations without manual handset handling.

Recommendations

For best audio clarity, install the unit in locations free from strong background noise and position it so the microphone faces the typical user area. Use a managed PoE switch to ensure stable power delivery and configure SIP credentials and network QoS settings on the VoIP platform to prioritise voice packets and reduce latency.
